1. Neither stepping motor turns. Consider the power circuit. Control signal input circuit, because the motor circuit problem can be basically eliminated.
2. The power problem is also relatively simple. Cut off the power supply V+ and V- of a group of drivers. General power aging.
3. The wiring problem is much more complicated. But it is also very intuitive, there is no occasional failure before the problem occurs. It's the machine that comes and goes. If so, you can be 100% sure of the problem.
4. Signal problems are more complex, but the probability of no two pulses is less. If one pulse controls two drivers, such problems are more common.
5. Emergency stop switch problem. If the emergency stop switch is broken, the motor will not move.
